9 AM–12 PM GMT for private banking and fund administration; 2 PM–4 PM for trust and legal contacts. Avoid the FTSE close window (4–5 PM) when back-office teams are processing.

01

Consider time zones

Ensure your call aligns with the local time zone so you never accidentally ring at an unreasonable hour.

02

Workday schedules

Most professionals are reachable 9 AM – 5 PM local time. Avoid the lunch window from 12–1 PM for the best pickup rates.
